You can export your CiviCRM Spark database by going to Administer > Backups. This should be sufficient to get started on your own instance, but you may need to also download CiviCRM extensions (CiviCRM will display errors on the admin pages telling you which extensions are missing, most of which are not critical).
The monthly fees do not have any HST, since the service is run from the United-States (assuming that by HST you mean Canada's taxes?).
Once you are ready to cancel, there are links in the monthly renewal emails to allow self-serve cancellation.
Please do not hesitate to contact us at firstname.lastname@example.org for any billing or cancellation questions.
